Abstract (en)
[origin: WO9912651A1] A flow-through microcentrifuge comprising a container (70) in which a sample (82) is placed, and a power source capable of rotating the container (70) around an axis. High speed rotation causes the components of the sample (82) to separate according to their respective densities. Pressurized gas (81), a flowing liquid, electromagnetism, or an engine can power rotation of the container. Speeds of the microcentrifuge can reach up to 600,000 rpm, with a corresponding increase in centrifugal acceleration up to 1,500,000 g. In addition to separation, the microcentrifuge can resuspend pelleted material in a liquid by rotating in one direction and then in the opposite direction, repeatedly. The microcentrifuge is also able to mix two or more reagents (118) using this method. Two or more microcentrifuges can be placed together in any configuration and run by the same power source. In the preferred embodiment, several microcentrifuges are used simultaneously to centrifuge samples in multi-well plates (114a, 114b).
